The Brow Serum targets the follicular bond structure at the brow root — the same disulfide and ionic bond system that drives hair growth elsewhere. By strengthening follicles and supporting the growth cycle, it increases density and length with consistent use.

The routine

Use it your way.

Clean and dry brows

Apply to clean, dry brows — ideally as the last step of your skincare routine, before or after moisturiser. Remove all makeup first.

Apply with the spoolie brush

Use the included spoolie to apply a thin, even layer from inner brow to tail. Follow the direction of natural hair growth.

Allow to dry fully

Give the serum 60 seconds to dry before applying any makeup or other brow products. The lightweight formula absorbs quickly.

Daily use for 4 weeks

Consistency drives results. Daily application for 4 weeks is when the clinically measured increase in density and length becomes visible.

What's inside

Nothing to hide.

Every ingredient is 100% naturally derived. No fillers, no synthetic additives, no ingredient you'd need to google to feel okay about.

Castor Oil

Certified Organic

The primary growth active — ricinoleic acid stimulates microcirculation at the brow follicle, supporting the growth cycle and strengthening the bond structure at the root.

Hero

Argan Oil

Morocco · Fair Trade

Penetrates the brow shaft to rebuild disulfide bonds and reduce shedding between growth cycles. Adds the deep conditioning that prevents breakage at the brow.

Hero

Peptide Complex

Plant-derived

Signal peptides that communicate with the follicle to extend the anagen (growth) phase and increase the rate of active follicle recruitment.

Active

Aloe Vera

Certified Organic

Anti-inflammatory base that makes the formula safe for daily use around the sensitive eye area. Soothes and calms while active ingredients work.

Active

Vitamin E

Plant-derived

Antioxidant protection that shields follicles from oxidative stress — key for supporting consistent growth cycle activity over time.
